clion 头文件,clion怎么添加头文件

Clion 中使用头文件定义类，源文件实现

include什么

导入头文件(.h)和源文件(.cpp)
Note: 只导入 源文件（.cpp） 也可以

CMakeLists.txt

手动添加

cmake_minimum_required(VERSION 3.15)project(HCpp)set(CMAKE_CXX_STANDARD 11)add_executable(HCpp main.cpp)add_executable(ElemType ElemType.cpp ElemType.h)

自动添加

#if ($HEADER_COMMENTS)/*** Author: ${USER_NAME}* Date: ${DATE}* TODO: * Describe: #if ($ORGANIZATION_NAME && $ORGANIZATION_NAME != "")* Copyright (c) $YEAR ${ORGANIZATION_NAME}#if (!$ORGANIZATION_NAME.endsWith(".")).#end All rights reserved.#end*/#end 代码

ElemType.h

/** * Author: Dgimo * Date: 2020/4/1 * TODO: * Describe: */#ifndef HCPP_ELEMTYPE_H#define HCPP_ELEMTYPE_H#include <iostream>class ElemType {public: int data; ElemType(); ElemType(int); friend std::ostream &operator <<(std::ostream &, const ElemType &);};#endif //HCPP_ELEMTYPE_H

ElemType.cpp

/** * Author: Dgimo * Date: 2020/4/1 * TODO: * Describe: */#include "ElemType.h"ElemType::ElemType() { this->data = 0;}ElemType::ElemType(int data) { this->data = data;}std::ostream& operator <<(std::ostream &out, const ElemType &e){ out << e.data; return out;}

main.cpp

#include <iostream>#include "ElemType.h"#include "ElemType.cpp"using namespace std;

int main() {
ElemType e = ElemType(10);
cout << e << endl;
return 0;
}
